摘要: Abstract In the field of aquaculture, optical sensor technology is beginning to provide alternatives conventional electrical sensor. Hence, development and characterization a multipoint quasi-distributed fiber for oxygen measurement reported. The system based on 1 mm core diameter plastic where sections cladding have been removed replaced with three metal complexes sol-gel films form sensing points. locations utilize luminophores that emission peaks at 385 nm, 405 nm 465 nm which associated each Interrogation through optic spectrometer incorporating narrow bandpass filter. sensors showed comparable sensitivity repeatability, as well fast response recovery towards oxygen.
